Income Tax Calculator India: New vs Old Regime
An income tax calculator for India helps salaried individuals estimate tax payable and compare the new tax regime with the old tax regime. The new regime generally offers lower slab rates with fewer deductions, while the old regime can still benefit people who claim deductions such as Section 80C, 80D, HRA and home loan interest where applicable. Enter annual income and eligible deductions to compare estimated tax under both options. This calculator uses simplified FY 2025-26 slab assumptions, standard deduction and 4% cess for quick planning. It does not replace professional tax advice because surcharge, special income, capital gains, exemptions and employer payroll rules can change the final liability.
